Title: Fingerprint collating method and device therefor
Inventor: KODA SHIGETO
IPC: G06T7/00
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To unnecessitate a processing searching an identity coordinate system by shifting an image, by specifying a Y-coordinate value imparting the maximum value of a cumulative value or a Y-coordinate value within a prescribed range imparting the maximum value as the spiral center line in the X-direction of a fingerprint image and collating the identity based on the partial fingerprint image including the spiral center line. SOLUTION: The inter-image arithmetic processed image of an XY two-dimensional original fingerprint image and the shift image that a fingerprint image is shifted by a prescribed quantity in the fixed direction of an X-coordinate is generated (401, 402, 403). A prescribed threshold processing is performed for the arithmetic processed image (404) and the cumulative value of the intensity of all the picture elements in the X-direction is prepared for every Y-coordinate or the prescribed range of the Y-coordinate (405, 407). The Y-coordinate imparting the maximum value of the cumulative value or the Y-coordinate value within the prescribed range imparting the maximum value is specified as the spiral center line in the X-direction of the fingerprint image (406, 408). Based on the partial fingerprint image including the spiral center line, identity is collated (409).  Therefore, a processing searching an identity coordinate system can be unnecessitated.

Filed: 1990-11-15
Abstract: PURPOSE:To attain the communication with various terminal equipments on the condition of called party charging by detecting and registering caller number information element in a setup message received from a line, confirming the restoration of a caller and using the registered caller number to make loopback calling. CONSTITUTION:A network 3 connects a telephone set 2 to an ISDN line 6 designated by a called party number in a setup message sent from the telephone set 2. A control section 10 of an exchange 8 searches the information element in the arrived setup message from a memory 11 and when the information is coincident with a stored password, the caller identification number in the memory 11 is checked, and when it is coincident, a call message is sent. A caller receives the message and restores itself once for waiting, then the exchange sends a loopback setup signal to the caller. When the telephone set 2 replies the call, the exchange calls the ISDN line 6 and the called telephone set 12 to make the talking between the telephone sets 2, 12 available. Thus, the charging is imposed onto the extension terminal equipment 12 being the apparent caller.

IPC: H02M1/06
Filed: 1993-12-09
Abstract: PURPOSE:To regenerate snubber energy and to reduce snubber loss by providing a snubber circuit comprising a capacitor and a resistor between the arms of switching elements on the low voltage DC power supply side and a snubber circuit comprising a diode and a capacitor on the high voltage DC power supply side. CONSTITUTION:Switching surge voltage generated from an output module 202 connected with a low voltage DC power supply 61 is absorbed by an output snubber comprising an output snubber capacitor 102 and an output snubber resistor 103 connected in series. The surge voltage and the snubber loss can be designed at low levels because the wiring between the low voltage DC power supply 61 and the output module 202 is short. Switching surge voltage generated from a positive pole module 201 or a negative pole module 203 connected with a high voltage DC power supply is suppressed by increasing the capacity of the snubber capacitor 101 and the snubber loss generated from the snubber capacitor 101 is regenerated by the high voltage DC power supply 6.

CONSTITUTION:The circuit is provided with a delay means 13 for an image signal, a detecting means 10 for detecting the phase shift quantity of a picture element clock and a horizontal synchronizing signal, and means 11, 12 for controlling a delay time of the delay means 13, based on a result of detection of the detecting means 10. In such a state, based on the phase shift quantity of the picture element clock and the horizontal synchronizing signal, the image signal is delayed, and the timing of the image signal is allowed to conform with the timing of the synchronizing signal. In such a way, the consumption of a noise and power is suppressed and the horizontal shift of an output image is suppressed without using a high frequency for the picture element clock.
